Subject: f2fs causes system stall
Date: Thu, 24 Apr 2014 00:00:59 +0200 [thread overview]
Message-ID: <2601952.jk1l5iHOJT@ax5200p> (raw)
Hi,
it took me a while to bisect a problem which causes my ARM (tegra2) netbook to
frequently stall for 5-10 seconds when I enable EXA acceleration (opentegra
experimental ddx). I can only guess that the offending commit 8618b88 "f2fs:
fix not to write data pages on the page reclaiming path" somehow causes high
kernel latencies which may interrupt/disturb the command stream to the gpu in
this particular case. Reverting this commit fixes the problem. Any hints?
Regards,
Marc
